Unfortunately TH-cam lowered the quality of the final image, so i've posted the Image into my community section for you guys to see in higher quality :)
I noticed you're shooting through an open window and there's a heat radiator/register just below the window. The rising warm air will affect the seeing conditions. Even if you turn off the heat source it will take a while for the heat to dissipate.
I didn’t even of this, I have actually moved house now and will be shooting from outside with every session from now on. So hopefully my seeing conditions improve slightly, cheers mate :)
Without a tracking mount, you still can take images at short exposure-times, like 1/4 s. M42 is bright enough as to allow for this. I have done this with my 190/1000 Mak-Newt when I did not have a tracking on my EQ5 yet. Simply capture a series of 1/4 s frames and put them into DeepSkyStacker. Any longer exposures at a focal length beyond 600 mm or so will definitely produce star trailing blur, obviously also in M42 itself. More than a second is too long, I'm afraid.
@@ASTR0FILMS There are some Mac applications out there that offer stacking capability, like Siril and Nebulosity. I cannot tell you anything useful about them though, as I only used DeepSkystacker on Windows, which works quite well with large stacks of images. Picking M42 was a good choice, as it is quite bright, so that short exposures are feasible. For most other deep sky objects, tracking is kind of mandatory.
@@Guido_XL sweet, ill have a look at them. yeah I did think M42 was a good target, especially for something like a dob, just to show what they are capable of doing
Using the "Rule of 500," the max exposure you could take is 0.4 seconds to avoid trails. However, you would be better to use a telescope mounted on a motorized equatorial mount to get a much better image
I'm in the southern Hemisphere.. Did Orion too a couple nights ago... we have fairly nice weather, and no light pollution.... we have a lot of wind though, and that screws with the tracking alot on my "Newtonian-cloud-maker-delux". When I still used my Canon, I loaded Magic-larntern on it, for doing amazing timelapses/ long exposures and whatnot, no need for a remote shutter at all...
Quite nice to see something like what I actually see through my telescope, rather than the high res, hours of integration images that some astrophotographers achieve. I mean they are very impressive, but don’t give a realistic impression of what you can actually see visually.
Ah thanks so much, your right it is nice to see, maybe one day I’ll be able to produce 15 hour long captures ahah, for now I’m happy with my Dob though
Have you tried shooting the andromeda galaxy? It’s bright enough to see with shorter exposures. It’s nothing special, just a blob, but it’s really cool nonetheless
I mean yeah true but that’s because of the shutter speed I was using and I didn’t want to pick up much noise/ star trailing. Really I need to stack images
Not sure if you are trolling us but just in case you are not. Use the 300 rule. 300 divided by 1200 (your focal length) is .25 of a second for your max exposure without tracking coz you have a dob. Lucky that it's a bright target so this will work with a high ISO. Take 10 or 20 shots as M42 drifts through the frame and then reframe and repeat. Once you have 100 or so take your darks and flats and stack everything in Deep Sky Stacker. If any of that does not make sense. Watch some You Tube videos until it does. You will find that you can produce a much better image. Have fun.
not trolling no aha. but thanks, this actually really helped, Ill try give this a go next time i manage to get outside, The image i showed in the video is only one photo, not stacked or anything so thats the reason its not great sadly :/
@@ASTR0FILMS Stacking would not fix that data. Your major issue are massive star trails due to over exposure with an untracked mount but you know how to fix that now. Good luck and post your new results.
This is the kind of videos I was looking for
It’s not a great video partly because I was new, but it give a more “realistic” view on what you see before processing

The weather has been pretty lousy in the UK lately, we managed to get out on Saturday night but the dew was horrendous.
Totally, it sucks :/

True, I need to find a stacking program for Mac and then I can get on to doing this, hopefully I can get some better results :)

@@ASTR0FILMS you could consider running a virtual machine with Windows and the stacking program. I see no reason why it shouldn't work.

I’ve just ordered the stellalyra 8 inch dob as it comes with a right angled finder and a cooling fan.can’t wait to get started!
Just a thought, try locking the the mirror up prior to exposure.
Do you have any electronic tracking on your dob?

yeah we’ve had quite nice weather here in the northern hemisphere, but winters kicking in now so lots of cloud and rain :/

I have, your right aha it is just a smudge on the screen but still really cool :)
Excellent video
Thanks dude :)
Bro te recomiendo no usar iso ya que te bajaría mucho la luz 👍 yo tengo un telescopio y con ISO baja mucho la luz
I usually crack the ISO quite high but for this session I was trying it with a lower ISO to see what the results were like, thankyou
Music name please?
It’s in the description
A bit dim objects, though

@@jodyschultz5870 thanks mate :)
thats not a nebula....thats a space station !!!!
only 32 seconds of orion nebula
Star trails
hello
:)
i hate clouds
Me too :/
